Marks obtained by ‘A’ in subject P, Q, & R together are approximately what percent of marks obtained by F in subjects S, T & U together ?

Solution

Marks obtained by A in :

P = (68/100)*70 = 47.6

Q = (84/100)*80 = 67.2

R = (77/100)*120 = 92.4

Total marks scored by A in subjects P,Q,R = 47.6+67.2+92.4 = 207.2

Marks obtained by F in :

S = (68/100)*125 = 85

T = (68/100)*75 = 51

U = (71/100)*150 = 106.5

Total marks scored by F in subjects S,T,U = 85+51+106.5 = 242.5

Required %age = (207.2/242.5)*100 = 85.44% = ~85%
